摘要： A magnetic tape cassette capable of improving sealing of the tape cassette when it is out of use, to thereby positively protect a magnetic tape arranged therein. The magnetic tape cassette includes an openable front lid and a rear lid arranged so as to cover a front opening of the tape cassette casing and is so constructed that the front and rear lids are provided with facing portions, respectively, which are arranged so as to face each other along an arc defined by the facing portion of the rear lid when the rear lid is pivotally moved relatively to the front lid to cover the protecting space for the magnetic tape and each lid is formed into an arc or slanting plane, resulting in the lids being closely associated with each other to a degree sufficient to ensure satisfactory sealing of the cassette when the front lid is pivotally moved to cover the opening of the casing.

摘要： A tape cassette has a case containing a pair of reels for winding magnetic tape. An outer lid is pivotally mounted on the case to open and close the outside of the passage through which the magnetic tape is stretched along the front of the case. An inner lid is pivotally mounted on the inside of the outer lid to open and close the inside of the passage through which the magnetic tape is stretched. A slide member is formed on the inner lid. A guide groove is formed in the case to guide the slide member. The slide member is made of material different from the edges of the guide groove.
